SPECIFICATION forming part of Letters Application filed August 4, 1898. Renewed Ma To all whom it may concern: I

Be it known that I, JAcoB' CARrENrEa-a citizen of the United States, residing at En terprise, in the county of Hocking and State of Ohio, have invented certain new and use} f ul Improvements in a Combined Harrow, Pulverizer, and Crusher and I do hereby declare the following to be a full, clear, and exact de: scription of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combined harrow, pulverizer, and crusher; and it consists, essentially, of a frame having joints intermediate of its length topermit a conformation to irregularities of ground surface and flexible connections extending across the joints to remove the draft strain from the pivots as much as possible, a toothed pulverizing-roller beingconfined in the frame,with depending harrow-teeth located in advance, on opposite sides, and in rear of the same, a crushingroller being also'rotatably mounted near the rear end of, the frame and havingan auto maticall'y-adj ustable scraper extending there- The invention further consists of the details of construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

The object of the invention is to combine in one machine a number of devices for successfully and successively carrying on a harrowing, pulverizing, and crushing operation by a single movement of the machine during a run thereof over acerta in tract of ground surface and avoid the use of separatemato accomplish the same result.-

In the accompanying drawings, Figure 1 is I a perspective viewof a combined machine embodying the invention. Fig. 2 is a side elevation thereof, showing apart raised. Fig. 3 is a bottom plan view. Fig. 4 is a central longitudinal vertical section. Fig. 5 is a transverse vertical section on the line :0 as, Fig. 3.

Referring to the drawings, wherein similar numerals are employed to indicate corre: sponding parts in the several views, the numeral 1 designates a frame composed of opposite longitudinally-disposed parallel side Patent no. 629,313, dated July 1a, 1899. y26,1899. Serial No. 718,424. (No model.)

bars unitedat the front by converging bars 2 and also provided with intermediate crossbar-s3. The side bars are formed of Wood and primarily separated near their front ends and pivotallyjointed,as at 4, the adjacent united ends being formed with tenons and slots, respectively, and therein are loosely fitted the opposite trunnions 5 of atoothed pulverizing-roller 6, rotatably confined between the said side bars. The openings 7, formed through the united parts of said'side bars, are slightly larger than the said trunnions, and in the outer portions thereof metallic sleeves S are fitted and form bearings for the trunof the openings is prevented.

. To the center of the front bara draft-chain or analogous device 9 is secured and extends over the forwardly-p roj ectin g converging bars 7 2, laterally-extending chains or other like devices 10 beingconnected to said bars and chain9. Across the pivot-joints of the side bars chains 11 extend from one part of each tot-he other to transfer the longitudinal draft strain and prevent direct concentration there'- of on thepi vots. These chains 11 are sufficiently taut to p'roducethe desired effect stated and also to reinforce the joints against lateral strain that might occur from an irregular movement or drag of thev entire machine or from a lateral slipping movement.

Depending from the cross-bars 3 and also from the side bars 1 are rigid barrow-teeth 12 of suitable formation and having any preferred means offastening, and in rear of the back cross-bar a crushing-roller 18 is mounted and has opposite end trunnions 14, freely movable in wear-sleeves 15, fitted in openings in adjacent parts of the side bars.

' On the side bars near the crushing-roller the lower ends of spring-arms 16'are secured and slightly curve rearwardly and, upwardly and have theends of a transverse scraperbar 17 attached thereto and provided with a front reduced edge, and in operation the said bar is pressed downwardly until the reduced edge thereof bears on thesaid crushing-roller and removes allearth that may adhere to the latter. After sufficient use of the bar pressure is released therefrom and the resiliency of the arms 16 restores it to normal position. w

The frame, cross-bars, and rollers are preferably formed of Wood, though metal can be used, if desired, and when the machine is resting on a level the points of the barrow-teeth,- the teeth of the pulverizing-roller, and the crushing-roller all touch the surface about equally under normal conditions. In its movement over ground to be'treated the front harroW-teeth first strike and partially break up the lumps or olods, the teeth of the pulverizing-roller are then pressed into and dragged through the same, the harrow-teeth behind the said roller next further comminute the broken lumps, and the crushing-rol-lerat the rear completes the breaking up of the remaining unbroken lumps. The joints of the side bars cause both the front and rear part of the frame and the parts carried thereby to conform to the irregularities of the surface traversed and effectually perform the desired operation. Also, as shown by Fig. 2, the front part of the machine can be thrown up to reduce its longitudinalextent for convenience in storage.

Many advantages will become apparent by the use of the machine set forth, and changes in the proportions, dimensions, and minor details of construction can be resorted to Without departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is- 1. In a combined device of the character set forth, the combination of a jointed frame having depending harrow teeth, a toothed pulverizing-roller and a rearcrushing-roller, the points of the harroW-teeth and teeth of the pulveriZing-rollerand the crushing-roller all normally resting equally on the surface of the ground.

2. In a combined device of the character set forth, the combination of a frame having opposite side joints and depending'harrowteeth, a toothed pulverizing roller having trunnions forming pivots for said joints, flexible connections extending across the joints on the outer sides of the same, a rear crushing-roller, and a draft-chain or analogous de vice attached to the front end of the said frame.

3. In a combined device of the character set forth, the combination with, a frame having joints formed in opposite sides thereof and provided with depending harroW-teeth, a pulverizing-roller and a crushing-roller, of a draft-chain attached to the front part of said frame, and chains extending across the outer sides of the joints of the frame.

4. In a combined device of the character set forth, the combination with a frame having depending harrow-teeth, a pulverizingroller and a crushingroller, of yielding arms attached to the frame on opposite sides of the crushing-roller and connected to a scraper= bar having a front reduced edge adapted to be pressed down on the crushing-roller to clean the same.

5. In a combined device of the character set forth, the com'binationof a frame having opposite side joints and depending harrowteeth, a toothed pulverizingroller having trunnions forming pivots for said joints, chains extending across the outer sides of said joints and connected at the opposite ends to portions of the frame respectively at the front and rear of said joints, adraft-chain or analogous device attached to the front end of the said frame, a crushing-roller at the rear of the frame, upwardly-extending springarms on opposite sides of said crushing-roller,

and a scraper-bar attached to the said springarms and adapted to be pressed down against the crushing-roller to clean the same.

In testimony whereof I aflix my signature in presence of two Witnesses.

JACOB CARPENTER.
